IP range and Regular Expressions - Have I got this right?

[stytagm]

Hi All,

I'm trying to filter out an IP range from my analytics package, but I'm hopeless with this sort of stuff, does this look right?

The range was given to me as: 194.153.105.0/23 Which I think translates to the range 194.153.105.0 to 194.153.109.255, is that correct? (Calculated using this page: http://jodies.de/ipcalc)

Next, I came up with this regular expression: (Edit: Based on this page: http://www.webmasterworld.com/analytics/3011116.htm)
^194\.153\.10([5-9])\.([0-9]¦1[0-9]¦2[0-9]¦3[0-9]¦4[0-9]¦5[0-9]¦6[0-9]¦7[0-9]¦8[0-9]¦9[0-9]¦1[0-9][0-9]¦2[0-4][0-9]¦25[0-5])

Does that look right? Unfortunately there's no real way of testing it, as I can't ping my analytics from specific IPs in the range, and I have no way of knowing if traffic outside this range is being filtered out that shouldn't.

Many thanks for your help guys,
Andrew.

PS I've actually changed this number from the real one because I'm paranoid, but it shouldn't affect the regex. (I only changed the first two octets)

Ok well I spotted one mistake myself, I was given 194.153.108.0/23 so the range should be 194.153.108.0 to 194.153.109.255

So the regex should be
^194\.153\.10([8-9])\.([0-9]¦1[0-9]¦2[0-9]¦3[0-9]¦4[0-9]¦5[0-9]¦6[0-9]¦7[0-9]¦8[0-9]¦9[0-9]¦1[0-9][0-9]¦2[0-4][0-9]¦25[0-5])

If you are filtering it out you don't need to be clever with the last section.

Filter out the three first octets, doesn't matter what is contained in the last if its 194.153.108/9

194\.153\.10[5-9]\.*

Keep it simple, if you're only filtering through IPs this is more than fine.

Thanks guys, I've gone with:

^194\.153\.10[8-9]\.*

Assuming I got the range right in the first place this should do the trick.
